Set wifi without changing mDNS

Issues
1

This is my first time with any LED controllers and set the wifi without writing down the mDNS or changing it. Is there a way to factory reset it without accessing the web portal/app? I have a domestic automation vegas lights LED controller.

You should be able to hold down GPIO0 for 30s to factory default if it’s a reasonably recent version of WLED.

Would i just run a jumper from a ground to reset here? Or would it be elsewhere on the board?

I would run a jumper from the pin labelled GPIO0 to GND.

Reading through other docs, 30s might be more than you need (but shouldn’t hurt).
